- Explicitly set all the toolchain <foo>_FOR_TARGET variables. GCC's default guess for CC, etc. happened to work with the powerpc64-gcc port, but fails when the binaries have a suffix like the '6' suffix in freebsd-gcc6. Setting these variables explicitly keeps GCC's build from having to guess. - Pull patches from freebsd6-gcc instead of powerpc64-gcc. - Use per-arch plists. - Simplify the post-install steps to keep the hard links the normal install performs and avoid renaming binaries. Keep links to 'cc' and 'c++'. Reviewed by: bapt (earlier version) Differential Revision: https://reviews.freebsd.org/D22594 |

# $FreeBSD$ How to cross build initial toolchain Example with sparc64 1/ install a cross toolchain pkg install sparc64-xtoolchain-gcc 2/ cross build world make CROSS_TOOLCHAIN=sparc64-gcc TARGET=sparc64 TARGET_ARCH=sparc64 buildworld 3/ install the world in a sysroot make CROSS_TOOLCHAIN=sparc64-gcc TARGET=sparc64 TARGET_ARCH=sparc64 installworld DESTDIR=/sysroots/sparc64 4/ build the required port $ cd base/binutils make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 package $ cd base/gcc make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 package the package are in base/gcc/work/pkg/*.txz and base/binutils/work/pkg/*.txz To add a plist for a new binutils target $ cd base/binutils make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 makeplist > pkg-plist edit the pkg-plist and remove everything which base does not provide via the elftoolchain
